Two new security related features to Blog about this week. First, Oracle Database 11g comes with a new view called DBA_USERS_WITH_DEFPWD. What is for you ask? This view will show you the user accounts that are assigned default passwords, like scott/tiger. You can therefore change those passwords and be more secure. This view has one column, USERNAME.
Also, passwords in Oracle Database 11g will be case sensitive now! When you upgrade, your old passwords will not be case sensitive, but the first time you change the password of an account after an upgrade it will become case sensitive. New accounts will be case sensitive out of the box. The parameter sec_case_sensitive_logon will be provided to disable/enable this feature.
One other note. All the features I'm discussing in this Blog at this point are from Beta code. They can change between now and the time production code comes out, so be aware.
More on this and many other Oracle Database 11g topics in my new book from Oracle Press, Oracle Database 11g New Features. Check it out!
